The robo-etch uses two stepper motors to control an etch-a-sketch. Our stepper motor controller interpolates the user's mouse movements; allowing for smooth flowing curves to be easily generated. You can use any PS-2 mouse with the robot-etch. You can also control the robot-etch through the DB-9 serial connector using a simple protocol.

Robo-Etch features:

• Includes everything shown here except for the mouse and Etc-a-Sketch toy.
• Smooth interpolation allowing for graceful curves.
• Built-in backlash compensation.
• No soldering required! Easy assembly!
• Use as-is or create your own stepper motor project!
• Write a computer program to control the robo-etch!
